Sharpening the Blade
When sharpening the blade, follow the original angle of
grind as a guide. It is extremely important that each
cutting edge receives an equal amount of grinding to
prevent an unbalanced blade. An unbalanced blade will
cause excessive vibration when rotating at high
speeds. It may cause damage to the mower, and it
could break causing personal injury.
Balancing the Blade
The blade can be tested by balancing it on a round
shaft screwdriver. Remove metal from the heavy side
until it balances evenly. It is recommended that the
blade always be removed from the adapter when
testing for balance.
Reinstalling the Blade
Before reinstalling the blade and the blade adapter to
the unit, lubricate the engine crankshaft and the inner
surface of the blade adapter with light oil.
• Be sure to install the blade with the side of the
blade marked “Bottom” (or with part number) facing
the ground when the mower is in the operating
position.
• Slide the blade adapter onto the engine crankshaft.
• Place the blade on the adapter. Be certain the
blade is aligned with, and seated onto, the blade
adapter flanges.
• Place blade bell support on blade. Make sure the
notches on the blade bell support are aligned with
the small hole in the blade and replace the hex bolt.
• Torque hex bolt to: 450 in. lbs. min., 600 in. lbs.
max.
NOTE: To ensure safe operation of your unit, the blade
bolt must be checked periodically for correct torque.
SECTION 9: OFF-SEASON STORAGE
The following steps should be taken to prepare lawn
mower for storage.
• Clean and lubricate the mower thoroughly as
described in the lubrication instructions.
• The use of a pressure washer or garden hose to
clean your unit is NOT recommended. Using these
may cause damage to electrical components,
spindles, pulleys, bearings, or the engine. The use
of water will result in shortened life and reduced
serviceability.
• Refer to engine manual for correct engine storage
instructions.
• Coat mower’s cutting blade with chassis grease to
prevent rusting.
• Store mower in a dry, clean area. Do not store next
to corrosive materials, such as fertilizer and rock
salt.
NOTE: When storing any type of power equipment in
an poorly ventilated or metal storage shed, care should
be taken to rust-proof the equipment. Using a light oil or
silicone, coat the equipment, especially cables and all
moving parts.
NOTE: Refer to the separate engine manual packed
with your mower for more engine related information.
